| Abstract: | This paper presents a study of the stability of biocompatible nanostructured TiO2 surfaces prepared on a Ti6Al4V alloy by anodic oxidation, and it considers changes in the contact angles of ethylene glycol and distilled water. In the first stage, we measured the changes in the contact angles of the TiO2 surfaces before and after sterilization. Then we examined the changes in the temporal contact angles of TiO2 surfaces in different environments. The surface energy was calculated from the measured contact angles according to the Owens - Wendt model. Stability is significant for providing and innovating biocompatible coatings.The morphology of the deposited layers was observed using a scanning electron microscope (SEM). |
